An expression that can mean anything means nothing; when you want to please everybody, you please nobody.

Enrico Fermi, the great Italian physicist, killed all the aliens in 1950 by asking this simple/innocent question: “if extra-terrestrials exist, where are they?” This question has become the Fermi Paradox.

Even though I am a science fiction fan I do agree with the skeptics that, Houston, we have a problem:

a) the search for extraterrestrial intelligence (SETI) program to detect radio transmissions from other civilizations has been a failure.

b) the question of the Great Silence remains unsolved; if life is common, why don’t we detect their radio transmissions?

I remember the thrill of hearing about it on a hot summer day in Iran; the moon has not looked the same since!

Unlike my father, I am a lousy philatelist (postage stamp collector) but I was able to find the above page I bought in 1994—on the 25th anniversary of “the big step”—among my loose leaves.

The Drake Equation—an attempt to estimate the number of extraterrestrial civilizations in the Milky Way with which we might come into contact— is still fascinating to me but I see its light getting dimmer with every “silent year”…

N = R* × fp × nE × fl × fi × fc × L

This once serious equation looks more and more like this cartoon from this very funny site:

To commemorate the 40th anniversary of Neil Armstrong’s historic walk on the moon, Google is offering Internet users a virtualtrip to the moon.

I empathize with Fermi’s passion for clarity. I am simply unable to let things be foggy. The Drake equation is literally meaningless because “an expression that can mean anything means nothing.”
